SU755309A1 - Magnetic separator - Google Patents

Description

The invention relates to the field of mineral processing.

A magnetic separator is known that includes a transporting body with a vibrator, a working body in the form of a drum made of a non-magnetic material located above it, with a magnetic system placed in it, a feeder and receivers of separation products [11 The disadvantage of this separator is the low efficiency the length of the working area, the sliding of magnetite particles on the working body and the lack of mixing of the ore mass on the transporting body.

The aim of the invention is to intensify the separation process by increasing the length of the working area and increase the efficiency of the process by increasing the working area.

This is achieved by the fact that in the proposed separator the drum is installed parallel to the longitudinal axis of the transporting body, provided with longitudinal ribs and a device for adjusting the gap between the transporting and working bodies,

and the vibrator is made in the form of rollers with unbalances.

FIG. 1 shows a schematic diagram of a separator for dry magnetic separation of highly magnetic ores and materials, a general view; in fig. 2 - section A — A on

^{5 of} FIG. one.

The separator contains a feeder 1, a transporting body 2, a drum 3 of a non-magnetic material, a magnetic (electromagnetic) system 4, a frame 5, rollers with

U unbalance 6, the longitudinal ribs 7, the receiver 8 concentrate, a device 9 to adjust the gap between the transport and working bodies.

The separator works as follows. The source material through the feeder 1

¹⁵ enters the transporting body 2, which transports it under the drum 3 into the working area of the magnetic system 4, which creates a magnetic field. In the working area of the magnetic particles in

₂₀ surface layer, are attracted to the drum 3 and are transported by the drum using the longitudinal ribs 7 to the concentrate receiver 8. Under the influence of rollers with unbalances 6 ore material

collapses and loosens, thanks to which the magnetite particles are transferred from the lower layer to the surface layer, from which they are extracted onto the surface of the drum 3. The gap between the drum and the transporting body is about m and f f e r e and r o n n regulate 9, a special device such ob- ⁵ again that as material moving along the drum and eject particles with high magnetic susceptibility, its value decreases.

The location of the drum, equipped with _1D longitudinal ribs, parallel to the longitudinal axis of the transporting body, the vibrator of which is made in the form of rollers with unbalances, as well as equipping the separator with a device for adjusting the gap between the transporting and the working and bodies provide increased intensity and efficiency of the process of dry magnetic separation of highly magnetic ores and materials .
